Heya
@_KenE,
This is something we've been discussing for some time now, but we've now decided to accept it!
We think that since the other games have dailies, it only makes sense to add some for 1v1 Arena. However, the rewards will likely be relatively low since 1v1ing a friend is easier than for example doing the other minigames. This will hopefully be done sometime in the near future!
Thank you for suggesting this and have a fantastic day!
